Enhanced Rich Text for SharePoint Extended
The ERTE project, hosted on Codeplex (http://www.codeplex.com/erte) is my open-source project, aiming to remove the problem that SharePoint has (especially in blogs). If you insert an embedded content (like videos from YouTube, MSN Video, Google Video, etc.), the code gets filtered out server-side.
Clicking that button will open an interface into which you can paste the “Embed” code provided by your media providers (like youtube, MSN Video, etc.).
Into “Alt text” field enter the text (or HTML) of what will be shown in the RSS Feed and in the editor.
If this simple addon saved you hours of troubles or hundreds of dollars, you can support further development by small donation.
